BROODER.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed November 10, 1913. Serial No. 800,234.

To all whom it may concern:

Be it known that I, OSCAR A. SGHRAMM, a citizen of the United States, residing at Delphos, in the county of Allen and State of Ohio, have invented certain new and useful Improvements in Brooders, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in brooders and has for its primary object to provide a brooder of improved construction and an automatic temperature regulating and ventilating system for the same.

Another object is to provide a brooder of this character having a compartment lined with non-heat conducting material and provided with means for automatically regu lating the temperature within said compartment and the supply of fresh air to said compartment.

A further object is to provide a brooder of this character, in which a predetermined temperature will be maintained at all times, regardless of the weather conditions and which will also be provided with means for preventing the heating lamp'of the brooder being extinguished by a strong current of air reaching the same.

A still further object is to generally improve and simplify the construction and operation of the various parts of the device and increase the efficiency of the same without materially increasing the cost thereof.

With the above and other objects in view, my invention consists in certain novel constructions, combinations, and arrangements of parts to behereinafter more fully described, claimed, and illustrated in the accompanying drawings, in which,

Figure 1 is a side elevational view with parts broken away; Fig. 2 is a front eleva tional view; Fig. 3 is a top plan view with the cover removed; Fig. 4 is a cross-sectional view on the line 44 of Fig. 3; Fig. 5 is a top plan view with the upper compartment removed; Fig. 6 is a fragmentary detail sectional view, showing the manner in which the fresh air dampers are mounted and adapted to be operated; Fig. 7 is a detail sectional view on the line 77 of Fig. 6; Fig. 8 is a fragmentary detail sectional view, showing the means for controlling the closure plate in the lamp compartment; and Fig. 9 is a fragmentary detail View showing the closure plate and foul air escape opening in the cover.

Referring more specifically to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 designates the heating compartment of my brooder which is heated by the lamp 2 within a chamber or inclosure 3 which is out of communication with the compartment 1. A continuous heating pipe 4 extends around the upper portion of the heated compartment 1, and has its opposite ends secured in the opposite side walls of the chamber 3, whereby the heated air from the latter may travel through the pipe 4 and thereby heat the compartment 1. The compartment 1 is lined with asbestos 5 or other suitable material to prevent the escape of heat, and the chamber 3 is also lined with asbestos 6 or the like for the same purpose. The compartment 1 is preferably connected with another compartment 7, indicated by dotted lines in Fig. 2, which may, if desired, be employed as an incubator compartment. If desired, the compartment 1 maybe connected with a series of other compartments which may or may not be heated.

The lamp 2 may be a kerosene lamp or one of any other suitable type, and access thereto is had through a door 9 hinged to the outer side wall of the compartment 1.

The floor of thechamber 3 is somewhat lower than the floor of the compartment 1,

the purpose of which will later appear.

The front and rear walls of the compartment 1 are provided with inlet openings 10, which have the shields 11 positioned thereover and secured in position by suitable means engaged through their offset longitudinal edges 11, it being understood that the opposite ends of the shields are open.

, Above the compartment 1 is an upper compartment 12, the floor 13 of which serves as the ceiling of the compartment 1. Secured to the upper face of the floor 13 is a pair of brackets 14, between which is rotatably supported a channeled rock bar 15, by means of pivots 16 that project beyond the ends of the bars and through the respec=v tive brackets 14. The bar 15 has an ear 17 projecting laterally from one edge engaged by the upper end of a vertical rod 18 which projects through the floor 13 and is connected at its lower end with the thermostat 19 which is secured to the under face of the floor 13, within the compartment 1, a suit able guard 20 being secured to the under face of the floor 13 around the thermostat 19 to protect the latter.

Parallel with the rock bar 15 is a rod 21 which has the set screws 22 threaded in its opposite ends, and extending through guide blocks 23 secured to the floor 13 adjacent to the end walls of the compartment 12 and through said floor. When the floor 13 is in horizontal position, the points of the screws 22 rest upon the heads of the vertical plns 24 which are loosely mounted in bracket arms 25 secured to the under faces of the front and rear walls of the compartment 1, the lower ends or points of said pins 24 being secured to the offset portions 26 of the horizontalrods 27 which are pivotally mounted upon the screws 28 and have their opposite ends secured to the dampers 29 within the fresh air inlet openings 10, whereby downward movement of the rod 21 and the screws 22 will cause downward movement of the pins 24 and turning of the rods 27 to open the dampers 29 to allow fresh air to enter the compartment 1. The ear 17 is prevented from moving upwardly upon the rod 18 by a nut 30 threaded upon said rod and bearing against the upper face of the ear 17. Downward movement of the ear 17 upon the rod 18 is also prevented by the rod 31 secured by one end to the bar 15 and resting transversely across the rod 21, said rod 31 having the weight 32 adjustably mounted upon the same. A pair of rods 33 is secured transversely through the upturned longitudinal edges 15 of the bar 15. One end of each rod 33 is loosely mounted upon the rod 21, near one end of the same, while said rod has its opposite end curved into substantially semi-circular form, as shown at 34, and secured centrally to a lid 35 above and adapted for engagement upon the upper end of a foul air outlet pipe 36 projecting through the floor 13, said pipe 36 preferably having a screen 37 positioned therein to prevent dirt from falling from the compartment 12 into the compartment 1. Longitudinal movement of the rod 21 is prevented by the collars 38 formed thereon inwardly of the ends of the rods 33 mounted upon said rod 21. A short rod 39 has one end secured through the flanges of the rock bar 15 while its opposite end is loosely connected with the rod 40, within the protecting housing 41. The rod 40 extends through the second housing 42 and is pivoted upon the rod 43 projecting transversely through said housing and serving to connect the upper portion of the housing with the upper portion thereof. The free extremity of the rod 40 has the screw 44 adjustably secured therein, said screw projecting through a suitable opening in the floor 13 and resting upon the head of the pin 45, which latter is slidably mounted in suitable bearings 46 secured to the inner face of the side wall of the compartment 1 and having its lower end secured upon the horizontal portion 47 of the rod 48, as shown at 49. The horizontal portion 47 of the rod 48 is beneath the floor of the compartment 1 and is pivoted in the bearing 50 secured to the under face of said floor, one end of the horizontal portion 47 projecting through the side of the lamp chamber 3 and connecting with the vertical portion of the rod 48 within said compartment 3. The upper extremity of the vertical portion of the rod 48 is directed horizontally until directly above the center of the lamp 8, after which it is bent upwardly for a short distance and secured to the closure plate 51, which is normally engaged against theoutlet opening 52 in the top of the chamber 3 and around which is engaged the inner end of the surplus heat escape pipe 53, said pipe being within the compartment 12 and having one end proj ecting through the front wall of said compartment and provided with a cap 54, through which is extended a vertical pipe 55, which vertical pipe 55 serves to direct the air currents directly through the cap 54 and thereby prevent said air currents from reaching the outer end of the pipe 53 and traveling through the same to extinguish the lamp. The pipe 55 has an opening 56, within the cap 54, in its side opposite that facing the end of the pipe 53,- whereby the heated air fed to the cap 54 by means of the pipe 53 may escape to the atmosphere by way of the pipe 55. The lower end of the surplus heat escape pipe 53 extending downwardly through the floor 13 has engaged thereon a plate 57 which is secured to the under face of said floor 13 and is adapted for engagement upon the top of the chamber 3 when the floor 13 is in horizontal position, said lower end of the pipe 53 engaging around the short pipe 58 projecting upwardly from the outlet opening 52 in the top of said lamp compartment.

The compartment 12 is secured in position upon the compartment 1 by hooks 59 and eyes 60 on the faces of the compartments 1 and 12, respectively, or by other suitable means, said compartment 12 being also provided with a handle 61 upon its front face, whereby said compartment may be readily swung to raised position upon its hinges 62 at the rear edge of said compartment. If desired, the compartment 12 may be formed with one edge, preferably the front edge, considerably higher than the opposite edge and the remaining edges inclined, as shown, whereby the roof 63 will be placed upon an incline and thereby causing rain and the like to readily drain off of one edge of said roof. The roof 63'is preferably hinged to the rear edge or lower edge of the compartment 12, as shown at 64. The roof is provided with a ventilation opening 65 having 3 vpipe 66, thereby controlling the escape of foul air from the compartment 12 and the entrance of fresh air to the same by means of the pipe 66. It will be understood that one end of the slide plate 7 0 is rolled over, as shown at 71, whereby said slide platemay be readily moved to proper position upon the plate 68 and will be prevented from sliding all the way through andwill be limited in its movement upon the plate 68. The slide plate 70 is also preferably provided with a longitudinal rib 72 to strengthen and reinforce said slide plate.

From the foregoing it will be clearly apparent that after the parts have been properly connected and the nut 30 and weight 32 properly adjusted, the temperature within the compartment 1 will be automatically controlled and prevented from rising or falling below a predetermined degree. This is accomplished as follows :When the temperature increases above a predetermined degree, the thermostat will expand and pull downwardly upon the rod 18, thereby drawing downwardly the ear 17 rocking the rock bar 15 to raise the lids 35. This rocking or tilting of the bar 15 will also cause downward movement of the rod 21 and screws 22 carried thereby, said screws 22 pressing the rods 24 downwardly and thereby rocking the rods 27 to open the dampers 29 which cover the fresh air inlet openings 10. This same movement of the bar 15 will move the rod 39 upwardly, which, in turn, will rock the rod- 40, forcing downwardly the pin 45 and swinging the closure plate 51 away from the outlet opening 52 in the top of the chamber 3. It will therefore be seen that the foul air may readily escape from the compartment 1 and fresh air enter the same to cause a drop in the temperature in said compartment, while the surplus heat escapes through the pipe 53.

It will be readily understood that as soon as the temperature decreases below normal, the thermostat will contract sufiiciently to force the rod 18 upwardly and thereby cause a reverse movement of the operative parts mentioned toreturn thelids 35 to their normal positions, above the foul air outlet pipe 36 and also allow the dampers 29 and the closure plate 51 to return to their normal po sitions.

I have provided a thermometer 72 carried by the supporting legs 73 removably engaged in ears 74 of the bracket 7 5 to support said thermometer in front of the window 76, whereby the temperature within the compartment 1 may be readily seen by the operator through said window 76 without opening the compartment 1.

An escape pipe 76' is connected by one end to the portion of the continuous heating pipe 4 at the inner side of the compartment 1. The escape pipe 7 6, after being extended through the wall of the compartment 1, is bent at a right angle and extended parallel with the portion of the continuous heating pipe 4 to which it is connected and has its free end extended beyond the front wall of compartment 1 and a cap 77, similar to the cap 54, secured thereon, as will be readily 1(1%d8ISt;)0d by referring to the drawings ig. 5 Y
